A low-cost, distributed broadband multi-service communication network includes intelligent hybrid communication nodes which communicate with one another. The hybrid communication nodes have multi-media interfaces and processors that allow the node to receive a communication broadcast at one protocol interface, convert the broadcast to other communication protocols, and route it to those different communication protocol interfaces for transmission to other communication media. The smart hybrid communication nodes provides a distributed system that does not rely on a central intelligence, so that the network can be instantly deployed and expanded. In addition, a weatherproof container permits the nodes to be physically mounted adjacent to a communication antenna. This eliminates the need for a cable to connect a transmitter interface to the antenna (which can be several hundred feet away at the top of a tower). Even expensive cable results in substantial power and signal loss.

Systems and methods for measuring dynamic hydraulic conductivity and permeability associated with a cell layer are disclosed. Some systems include a microfluidic device, one or more working-fluid reservoirs, and one or more fluid-resistance element. The microfluidic device includes a first microchannel, a second microchannel, and a barrier therebetween. The barrier includes a cell layer adhered thereto. The working fluids are delivered to the microfluidic device. The fluid-resistance elements are coupled to one or more of the fluid paths and provide fluidic resistance to cause a pressure drop across the fluid-resistance elements. Mass transfer occurs between the first microchannel and the second microchannel, which is indicative of the hydraulic conductivity and/or dynamic permeability associated with the cells.

A form of the invention is applicable for use in conjunction with a6 security credential management system that produces and manages pseudonym digital certificates issued to vehicles and used by vehicles to establish trust in vehicle-to-vehicle communications, the security credential management system including a pseudonym certificate authority processor entity which issues pseudonym digital certificates to vehicles, a registration authority processor entity that validates, processes and forwards requests for pseudonym digital certificates to the pseudonym certificate authority processor entity, and a misbehavior authority processor entity that receives misbehavior reports from reporter vehicles that include information about the reporter vehicles and suspect misbehaving vehicles and is responsible for producing a list of revoked credentials; the pseudonym certificate processor entity and registration authority processor entity participating in producing linkage values to be contained within the issued pseudonym digital certificates, the linkage values being derived ultimately, using a one-way function, from linkage seeds thereby enabling, in predetermined circumstances, at least some of the certificates containing linkage values derived from a given linkage seed to be revoked. A method is set forth for improving operation of the security credential management system, including the following steps: in conjunction with deriving the linkage values from the linkage seeds, additionally producing encrypted linkage maps that relate, in encrypted form, linkage values with linkage seeds from which they are derived; determining particular linkage values deemed to be of interest based at least in part on information derived from misbehavior reports; and determining linkage seeds associated with the particular linkage values utilizing decryptions of the encrypted linkage maps.
